__APPLE__ is usually the only define you should really be depending on 
(other than things you pass in yourself via configure).

If you're getting the NSLinkModule -> mmap crash, then yes.  It's the 
multiply defined symbol that kills it (system in postmaster, system in 
libSystem).  The other crashes I saw were related to the shared mem 
limit that you can only set *once*.. so you have to sudo vi /etc/rc 
instead of /etc/sysctl.conf :(
